Nutrex Muscle Infusion is a blend of seven, multifunctional, diverse yet complimentary, muscle-building proteins. This combination provides an initial surge of Branch Chain Amino Acids that is derived from Whey Protein Isolate and Hydrolyzed Whey Protein. It’s then followed by the Sustained Release of amino acids to keep your muscled fed for several hours after drinking it. 

Hydrolyzed Whey is created by using enzymes to “pre-digest” Whey Protein Concentrate molecules. These molecules are split into readily absorbable peptides that bypass the stomach and can be immediately absorbed by the small intestine. So it gets to work to repair the deliberate damage that you’ve done to your muscle tissue during training immediately.

Nutrex Muscle Infusion also has essential vitamins and minerals added to it, in addition to extra BCAA’s and Glutamine all of which combined should give you a muscle building advantage. Also included in the special protein blend are Whey Protein Concentrate, Egg Albumin, Micellar Casein, Milk Protein Isolate and Calcium Caseinate. The Micellar Casein maintains amino acid levels up to 7 hours after your workout. Calcium Caseinate is another Sustained Release protein that has the added benefit of contributing a rich and creamy texture to your protein shake. This blend of protein contains immune-boosting agents Alpha-Lactalbumin, and Beta-Lacto Albumin. 

Nutrex Muscle Infusion is an excellent protein powder within its Sustained Release category. If you’re interested in this kind of multi-protein matrix product it’s worth comparing to Optimum Nutrition’s Hydro Builder and PVL Mutant Pro.
